Hello All, it seems i have a lot of oil coming out of the valve cover nipple and i am finding a lot of oil being sprayed all over the place from the airbox area where the hose connected to the nipple goes into the airbox. I have found puddles of oil in the airbox as well and found some oil near the nipple on the valve cover. can you please help me resolve this issue? I was thinking about buying the Positive Crankcase Ventilator from scrappy dogs but have no clue how it works or to install. image of my issue, please note the airbox was disconnected when I toke the picture.  Positive Crankcase Ventilator Have, or are you removing your airbox?Is your scoot blowing oil? Have you run dry and don't know why? The reason may be that excessive pressure is being built up in your crankcase, which blows seals and/or pumps all your oil out the vent. This nifty device actually creates a vacuum within your engine by only allowing air out, and not back in. Made in the USA all steel construcion easily attaches to your vent line, which should be place above your engine as far as possible, and installed on the barbed nipple end. Threaded end is left open, or attached to a filter if you wish. This is a must if your running your scoot full throttle alot. New improved model. Cheapest performance fix anywhere at only $9.  thank you |

I might as well ask . how do you measure your oil level when adding oil ?

Cheapest performance fix anywhere at only $9. thank you I bought one of Scrappy's PCV valves about a year ago ---- only to hear AllyOop (one of the moderators here) say it was a useless device that is silly to install. But if you are getting so much blowback it's actually blowing back into the filter box there is a significant problem. As GEH said, maybe you added way too much oil. If not, you may have a failed piston ring (which lets high pressure combustion gasses slip past the piston into the crankcase, pressurizing it and forcing oil out wherever it can). And drop in performance? Any smoke out the exhaust? Have you checked compression? |

I use about 750ml of oil. I did not do a compression test don't have the tool.  Performance is very good |

Since I have removed my air box and PAIR system I had nothing to attached to the hose coming from the Valve cover.
I did install a PCV valve.
There is still a Very Slight mist that comes from this PCV.
My riding is mostly rural so I'm at WOT or close to it much of the time.
I hope for your sake you do not have a Cylinder, Piston assy problem.
What type/brand of Oil are you using?

Something just came to mind from one of your earlier posts.
You initially used Synthetic oil on the Brand new BBK.
I noted this and you were going to change to Dino Oil for the rest of the top end break in.
Ive had issues in the past with going to Syth, to quickly and found it nearly impossible to seat the new rings to the new bore. Had to use a Dyno with a break to really crank down on engine load that could not be duplicated on the street to seat the new rings.
I sure hope this is not your problem of excessive blow by caused by initial start up and run with Synth Oil.

I sure hope this is not your problem of excessive blow by caused by initial start up and run with Synth Oil. I used 0w-40 Synth Mobil1 to break in the new rings I put in mine recently. Was all I had at the time. Drove my 100 to break in the new rings, got paid, then changed out to 10w-40 SAE Pennzoil. The old oil looked as to be expected, had lots of very tiny "glitter dust" in it like it should have after breakin. I rode most of the 100 in one day though so that may be the key factor as to why the lightweight synth worked for me for this. |

Flex Hone or Three Finger Stone Hone? What # Grit on the Hone you used? |

The 970cc BB Sport Bike was mounted to a Dynomometer that incorporated a Brake. With the Brake I could Crank down on Engine Load from WOT and make Her Cry. The Pipe went from Slight Black/Sooty to White, WOOOla, Sealed it up. Next to impossible if not impossible to Duplicate that Engine Load on the Street. Just can't do it. A Dynomometer similar to this is used on Automotive Race engines to carefully break a engine in with a specific procedure so once the engine is ready for the race car she is ready to race. Ill go into some more details once the above few questions are answered. |

I can create load fairly easy i would think on this 170cc  , however I am not seeing any smoke. |

Don't know why you would not do a simple compression test.
Most of the auto parts stores have free loaners of testers ...
